Perennial phlox 'Uspekh' Phlox paniculata 'Uspekh'

Water

Garden Phlox should be watered deeply once a week, providing about an inch of water each time. During hot, dry periods, increase watering to twice per week. Avoid overhead watering to prevent foliar diseases, instead, use soaker hoses or drip irrigation to deliver water directly to the base of the plant. Make sure the soil is moist but not waterlogged. Over the course of a month during the growing season, aim to provide approximately 4-6 gallons of water per plant, spread evenly across weekly watering sessions.

Light

Garden Phlox thrives in full sunlight, receiving at least six hours of direct sun each day. The ideal spot for this plant is in an area with bright, unfiltered sunlight, which encourages plentiful blooms and a strong, healthy growth habit. However, in extremely hot climates, Garden Phlox may benefit from light afternoon shade to protect it from the high heat.

Temperature

Garden Phlox prefers a temperate climate with temperatures ranging between 60°F and 85°F for ideal growth. It can withstand temperatures down to about -30°F in winter dormancy. It is important to keep the plant in a location where the temperature does not exceed 90°F for extended periods to prevent stress and potential damage to the plant.

Pruning

Garden Phlox benefits from pruning to promote vigorous growth and prevent disease. Deadhead spent flowers regularly to encourage a second bloom. After the flowering season, cut back the stems to about 1 to 2 inches above the ground. The best time for this major pruning is in late fall or early spring before new growth begins.

Cleaning

As needed

Soil

Garden phlox thrives in rich, moist soil with good drainage and a pH of 6.0 to 7.0. A soil mix with compost and loam is ideal for nourishing the plant and supporting its robust growth.

Repotting

Garden phlox is a perennial and does not require frequent repotting. It should be divided and replanted every 3 to 4 years to maintain vigor and prevent overcrowding.

Humidity & Misting

Garden phlox prefers moderate humidity levels but is adaptable to various conditions as long as it has good air circulation to prevent disease.

Suitable locations

• Indoor

  Ensure bright light and ample airflow for indoor garden phlox.

• Outdoor

  Plant in a sunny spot with well-draining soil for outdoor garden phlox.

• Hardiness zone

  4-8 USDA

Life cycle

Phlox paniculata 'Uspekh', commonly known as garden phlox or perennial phlox, begins its life cycle as a seed sown in early spring or by root cuttings. After germination, the seedlings develop into a rosette of leaves close to the ground, gradually forming a sturdy root system. With sufficient sunlight and nutrients, the plant advances to the vegetative stage, producing tall, erect stems with lanceolate leaves and branching out to create a bushy growth habit. During the summer months, usually between July and September, garden phlox enters the flowering stage, showcasing dense clusters of fragrant, vibrant flowers in hues such as pink, red, purple, or white. After pollination by insects, particularly butterflies and moths, the flowers give way to seed capsules that ripen and release seeds, facilitating the dispersal phase of the life cycle. Garden phlox completes its annual cycle by dying back to the roots in winter, surviving as a perennial with the ability to regenerate and flower in the following growing season.

Propogation

• Propogation time

  Late Spring to Early Summer

• The most popular method of propagation for Phlox paniculata 'Uspekh', commonly known as Garden Phlox, is by division. This technique is usually performed in early spring or late summer after the blooming period. Gardeners dig up the plant, gently separating the root ball into sections, each with a portion of roots and shoots. These divisions should be replanted promptly at the same depth they were growing at before, spaced approximately 15 to 18 inches (about 38 to 46 centimeters) apart to allow ample room for growth. Water the new divisions thoroughly after planting to help establish them. This method of propagation helps to rejuvenate older clumps that may have become woody and less floriferous.
